3D multiscale segmentation and morphological analysis of x-ray microtomography from cold-sprayed coatings

Summary X‐ray microtomography from cold‐sprayed coatings brings a new insight on this deposition process. A noise‐tolerant segmentation algorithm is introduced, based on the combination of two segmentations: a deterministic multiscale segmentation and a stochastic segmentation. The stochastic approa...

Description
Summary:Summary X‐ray microtomography from cold‐sprayed coatings brings a new insight on this deposition process. A noise‐tolerant segmentation algorithm is introduced, based on the combination of two segmentations: a deterministic multiscale segmentation and a stochastic segmentation. The stochastic approach uses random Poisson lines as markers. Results on a X‐ray microtomographic image of aluminium particles are presented and validated.
